TACK-STRIP-SET- TING MACHINE.

SPECIFICATION forming part of Letters Patent No. 431,549, dated July 8,1890.

I Application filed April 8,1890. Serial No. 347,032. (No model.)

To all whom it may concern:

Be it known that I, MATTHIAS BROOK, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in Tack- Strip-SettingMachine, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to provide a tack-strip -settingmachine -with means whereby the machine may be automatically stoppedunder various conditions-as, for instance, when the paper strip breaksbetween the usual delivery-reel and the roadway, or at or near the pointat which the tacks are driven into the said strip, or when the paperbunches up between the point where the tacks are driven into it and thepoint where the headcovering strip is applied to the strip containingthe tacks.

Prior to my invention certain feelers and devices for stopping themachine when the tack-strip breaks. at or near the point where the tacksare being driven into it or when the said strip bunches up, have beencarried by a rod parallel to the driver-bar, as in the machinerepresented in application Serial No. 334,070; but in such constructionit is difficult to get at the parts, and the said feelers have to bemade light and thin, and consequently they do not at all times have thenecessary strength, and very considerable trouble is caused in gettingat and removing the parts in case of breakage.

provided the usual rising and falling table or bed carrying the racewayfor receiving the bodies of the tacks and for supporting the body-stripwith feelers, and between the said feelers and an arm connected withtheusual tripping-bar I have interposed lifting devices actuated by thesaid feelers to lift the tripping-bar at the proper time. The driver-barhas a projecting 'finger, which, at each descent of the driver, actsupon the rear end of that feeler which bears upon the tack-stripclose tothe point where each tack is driven into it, the finger acting to liftthe end of the said feeler when the body-strip is to be fed under it,the said feeler being the only one In accordance with this myinvention Ihave.

which normally rests in contact with the bodystrip. I have also providedthe machine with a feeler which bears upon the head-covering strip andacts .upon the lifting device'de-' scribed whenever the head-coveringstrip is broken.

Figure l is a front elevation of a sufficient portion of ataek-strip-setting machine of usual construction with my improvementsadded to enable my invention to be understood, the driver being shown inits lowest position. Fig. 2 is a partial side elevation of the machineshown in Fig. 1; Fig. 3, an'enlarged inner side view of the feelers, thelift ing device, the raceway, and part of the tripping-bar; Fig. 4, aleft-hand end view of Fig.

247,143. The machine shown in the drawings also contains a reel N forthe covering-strip H, a rest 10 for the strip, and a paste-box 14,having a paste-roll 13, as in United States Patent No. 402,058.

In accordance with this invention I have applied to the raceway E asuitable upright 20, upon which I have pivoted at 21 a feeler 22, havinga lug'23 extended upwardly from its rear end, the forward end of thesaid feeler being rounded and normally resting upon the body-strip Hquite close to the point at which the tack is driven into the saidstrip. The right-hand end of the feeler 22 is normally kept upon thebody-strip by a spring 24, one end of which is connected to the saidstand; but just about as the strip is to be fed in usual manner by theaction of some suitable feeding device against a tack driven into thebody-strip, or in some other usual way, a finger 25, connected to thedriver-bar e and ris ing and falling in unison therewith, strikes therear end of the said feeler as the driver completes its descent andlifts its front end from the strip, so that the latter may be fedwithout any detention from the feeler. stand referred to also haspivoted upon it an auxiliary feeler 26, having two projections 27 and 28and an upright projection 29, the latter standing directly behind theprojection 23 of the feeler 22.

The under side of the raceway E is pro- Vided with a suitable stand30,between or on which is pivoted a lever-31 having at one end a finger32, which is extended over the bodystrip near the right-hand end of theraceway where the said strip comes upon'the raceway ingoing'throughthe'machine, the said finger lying on the strip between aplate 33 and the end of the raceway, the plate being between the reelfrom which the body-strip is taken and the raceway. The rear end of thelever 31 is also bent upwardly and provided with a finger 43, which isextended over across the raceway and the body-strip thereon and betweenthe said strip and the projection 28 of the auxiliary feeler 26 at therear of the point where the tacks are driven into the bodystrip. v

The

tions 23 and 29 of the two feelers 22 and 26.-

The upper arm 36 normally stands close to a stud or projection 39 (seeFig. 3) at the rear side of the arm f, connected to the lower end of theusual releasing-rod f, and the arm 37 is herein-represented as taperedat its end to constitute a wedge.

The slide I) referred to hasa wedge-shaped spur 2, which at eachreciprocation of the said slide passes either above or below thewedge-shaped point of the arm 37, it passing above the said point whenthe body-strip is in proper condition and below the said point wheneither the body-strip has run out or been broken or is bunched up, orwhen a tack has been but partially driven therein and its head sticks upabove the body-strip.

In operation, in case the body-strip breaks between the reel N and theraceway or is exhausted so as not to cover the raceway at its receivingend the finger 32 of the feeler 31 being no longer supported by the saidbodystrip descendsunder the action of the spring 40, connected theretoand to some fixed part of the machine, causing the finger 43 and theleft-hand end of the feeler 31 to rise and lift the arm 28 of theauxiliary feeler 26, so that the projection 29 thereon hits the arm 38of the lever Z and turns it on its pivot, so that the projection 2 onthe carriage b strikes the under or wedge-shaped end of the arm 37,which causes the said lever Zto be turned far enough to cause the arm 36to strike the projection 39 of the arm f and lift the releasingrod f toeifect the stopping of the machine in usual manner. may be lifted eitherby a bunched-up portion of the body-strip striking against theprojection 27 or against the projection 28. The auxiliary feeler 26 hasa forwardly-extended arm 44, which (see Fig. 1) terminates close to thespring 0 attached to the nose w at that side next the said arm.

In case a tack is not driven down into the body-strip for the properdistance the upper end of the tack above the strip will in the movementof the strip act on the jaw 0 and the latter will push out the spring 0far enough to hit the arm 44 and turn the auxiliary feeler, asdescribed, to effect the stopping of the machine. I

In case the body-strip breaks at or under the right-hand end of thefeeler 22 then the projection 23 of the said feeler rises and strikesthe arm 38 of the said lever l and turns it, as before described, sothat the wedge 2 again comes under the wedge-shaped point This sameauxiliary lever the said covering-strip breaks the said feeler 47 drops,turning the head and causing a proj cc.- tion or finger 48 thereon tostrike a pin 49, projecting from the rear side of the lever l, whichacts to turn the said lever far enough to place the beveled end of thearm 37 in position .to be acted upon by the projection 2 of the slide b,to again turn the lever Z sufiiciently to stop the machine.

Vhen the table-plate and raceway-bar are raised or lowered in usualmanner by the cam d, the feelers 22, 26, and 31 rise and fall in unisontherewith.

I do not desire to limit my invention to the exact shape shown for theleverl or to the bevel of the arm 37.

I claim-- 1. In atack-strip-making machine, the raceway-bar, combinedwith afeeler 22, connected to and moving in unison therewith,substantially as described.

2. In a tack-strip-making machine, the raceway-bar, combined with thefeeler 26, connected to and adapted to rise and fall in unisontherewith, substantially as described.
